【摘要】 在深井、超深井钻井过程中,套管磨损是个不容忽视的问题。文章概述了近年来套管磨损的国内外研究现状,指出了目前套管磨损理论及试验方法在解释深井、超深井套管磨损规律时存在的问题,提出通过模拟试验,在实验室受控条件下“再现”深井段的套管磨损行为,从而对深井、超深井的套管磨损机理进行分析。并明确了套管磨损机理及试验方法的发展趋势。更多还原

【Abstract】 Casing wear problem can’t be neglected during the drilling of the deep & ultra-deep well.In this paper the recent study of the research of the casing wear at home and abroad is reviewed.The paper indicates that the existing casing wear theory and test methods present some problems in explaining the casing wear behavior of deep & ultral-deep well,so the simulative test simulating the casing wear behavior of deep well in laboratory is proposed,and then the casing wear mechanism in deep &ultral deep well is analyzed.In this paper the development trend of casing wear mechanism and test methods is discussed as well.更多还原
